Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "up", "down", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the shaft sleeve machining fixture comprises a claw disc 1, wherein one side of the claw disc 1 is connected with a plurality of clamping jaws 3 in a sliding mode through a sliding groove 2, a mounting seat 4 is fixed to the other side of the claw disc 1, a driving assembly is arranged in the mounting seat 4, and the driving assembly comprises a threaded rod 5, a moving block 6 and a plurality of connecting rods 7.

The threaded rod 5 is fixed in the mounting seat 4 through a bearing 8, and the upper end of the threaded rod 5 penetrates through the mounting seat 4 and is fixedly connected with the rotary table 9; the moving block 6 is sleeved on the threaded rod 5 and is in threaded connection with the threaded rod 5; the upper end of the connecting rod 7 is hinged with the moving block 6, and the lower end of the connecting rod 7 is hinged with the tops of the clamping jaws 3 respectively; the side wall of the mounting seat 4 is provided with a moving groove 10 for the connecting rod 7 to pass through.

The spout 2 is around the axis evenly distributed of threaded rod 5, and the length direction of spout 2 is perpendicular with the axis direction of threaded rod 5. When rotating carousel 9, threaded rod 5 rotates along with it, and movable block 6 can reciprocate along threaded rod 5 to make connecting rod 7 take place to rotate, jack catch 3 can be close to each other or keep away from under connecting rod 7's effect, and the axle sleeve 11 chucking that will treat processing is fixed, can also effectively prevent to crush axle sleeve 11 when simple structure, convenient operation.
